  • Patent number: 9368166
    Abstract: A nonvolatile memory device includes a cell array including a plurality of cell strings extending on a substrate in a vertical direction, a page buffer connected to a plurality of bit lines and configured to store sensing data of the cell array in a sensing operation, a voltage generator configured to provide voltages to a plurality of word lines and the plurality of bit lines, and an input/output buffer configured to temporarily store the sensing data received in a data dump from the page buffer and to output the temporarily stored data to an external device. The nonvolatile memory device further includes control logic configured to set a status of the nonvolatile memory device to a ready state after the sensing data is dumped to the input/output buffer and before recovery of the cell array from a bias voltage of the sensing operation is complete.

  • Patent number: 9202587
    Abstract: A method of programming a nonvolatile memory device comprises performing an N-th program loop based on state data stored in data latches according to a default state ordering, determining whether conversion of the default state ordering is required according to a predetermined criterion, as a consequence of determining that conversion of the default state ordering is required, converting all or part of the state data stored in the data latches from the default state ordering to another state ordering, and performing a (N+1)th program loop based on the converted state data.

  • Publication number: 20140025866
    Abstract: A method of programming data in a nonvolatile memory via a first memory cell group and a second memory cell group in a page of memory cells includes; executing a first program operation that programs the first memory cell group with a first program voltage that is stepwise adjusted by a first increment over successive programming loop iterations, and thereafter executing a second program operation that programs the second memory cell with a second program voltage that is stepwise adjusted by a second increment over successive programming loop iterations, wherein the first program voltage is different from the second program voltage.
